What to do if SICC Tech CMAX has no or poor sanitary hot water production?

  Tiffany HernandezAug 5, 2025
  If your SICC Tech Water Heater isn't producing enough hot water, several factors could be the cause. First, too much air in the primary circuit might be the problem; try venting the circuit and installing an automatic air valve if one isn't present. Another cause could be a limestone-encrusted exchanger, which would require cleaning. A hole in the exchanger could also be the cause; check for leakage by disassembling the primary circuit, pressurizing the secondary circuit, closing both the inlet and outlet, and using a pressure gauge to monitor pressure changes. If there is a leak, replace the heat exchanger. Finally, excessive pressure from the supply network could be the issue, which can be resolved by installing a pressure reduction filter.

Why is there too much pressure in the secondary circuit of my SICC Tech CMAX Water Heater?

  Excessive pressure in the secondary circuit of your SICC Tech Water Heater could be due to a missing or insufficient expansion tank, or inadequate pressure within the existing tank. If the pressure increases as the temperature rises, it's important to check the presence and pressure of the expansion tank.

Why is the anode wearing out so fast in my SICC Tech CMAX?
- C
  Cheryl SnyderAug 25, 2025
  The anode in your SICC Tech Water Heater might be wearing out quickly due to excessive free surface needing protection, which results from stress on the internal anti-corrosion coating. To fix this, replace the cylinder.
